Description

Annular cutting edge woodworking white steel lathe tool

Technical Field

The utility model belongs to the technical field of the processing cutter, especially, relate to a annular cutting edge carpenter uses white steel lathe tool.

Background

A turning tool is a tool for turning machining having a cutting portion. Turning tools are one of the most widely used tools in cutting machining. The working part of the turning tool is a part for generating and processing chips, and comprises a cutting edge, a structure for breaking or rolling up the chips, a space for discharging or storing the chips, a channel of cutting fluid and other structural elements. The cutting part of the turning tool consists of a main cutting edge, an auxiliary cutting edge, a front tool face, a main rear tool face, an auxiliary rear tool face and a tool sharp corner. The cutting portion and the shank portion (i.e., the clamping portion) of the turning tool are coupled in a manner that is mainly integrated, welded, mechanically clamped, and welded-mechanically clamped. The mechanically clamped turning tool can avoid the stress and the crack of the hard alloy blade during high-temperature welding, and the tool holder can be used for multiple times. The mechanically clamped lathe tool is one with indexable insert and has insert clamped by screws and pressing board. The cutting part of the turning tool is composed of a main cutting edge, an auxiliary cutting edge, a front tool face, a rear tool face, an auxiliary rear tool face and the like. The geometrical shape of the cutter is determined by a front angle, a back angle, a main deflection angle, an edge inclination angle, an auxiliary deflection angle and a cutter point arc radius. The selection of the geometrical parameters of the turning tool is influenced by various factors and must be selected according to specific conditions. The rake angle is selected according to the composition and strength of the workpiece material, and should be a smaller value when cutting a material having a higher strength. The arc radius and the secondary deflection angle of the tool nose are generally selected according to the requirements of the roughness of the machined surface. The edge inclination angle is determined according to the required chip discharging direction and the edge strength. The pattern of the front face of the turning tool depends primarily on the nature of the workpiece material and the tool material. The simplest type is a flat type, and a flat type with a positive rake angle is suitable for a high-speed steel turning tool and a hard alloy turning tool for finish machining. The cutting part of the turning tool consists of a main cutting edge, a secondary cutting edge, a front face, a back face, a secondary back face and the like. The pattern of the front face of the turning tool depends primarily on the nature of the workpiece material and the tool material. The plane with the negative rake angle is suitable for processing hard alloy turning tools of high-strength steel and rough cut steel castings. The plane with the chamfer is a hard alloy turning tool which grinds a negative chamfer on a positive rake plane to improve the strength of a cutting edge and is suitable for processing cast iron and common steel parts. For the turning tool requiring chip breaking, a circular arc surface type with a negative chamfer can be used, or a chip breaking table is ground on the front surface of a plane type. Turning tools can be divided into outer circles, shoulders, end faces, grooving, cutting, threading, forming turning tools and the like according to purposes. And a turning tool specially used for an automatic line and a numerical control machine tool. A turning tool is mounted on a lathe for cutting a metal material. Turning tools include high-speed steel turning tools, ceramic tools, hard alloy turning tools, cubic boron nitride turning tools and the like. Turning tools are the most widely used ones. And is also the basis for learning and analyzing various cutters. The turning tool is used for various lathes to machine excircle, inner hole, end face, screw thread, turning groove and the like, and can be divided into an integral turning tool, a welding turning tool, a machine clamping turning tool, an indexable turning tool and a forming turning tool according to the structure. The indexable turning tool is increasingly widely applied, and the proportion of the indexable turning tool in the turning tool is gradually increased. Cemented carbide welding turning tools are so-called welding type turning tools. The mechanically clamped turning tool is a turning tool which adopts a common blade and clamps the blade on a tool bar by a mechanical clamping method.

At present, the existing turning tools on the market are used for processing most industrial metal materials, and the types of the turning tools required by some special processing of woodworkers are few, so that an annular-blade white steel turning tool for the woodworkers is provided.
